Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the laser ranging sensor is used for continuous detection in a high temperature working environment, then the productivity is improved, but the temperature of the detection device continues to rise causing detection accuracy to decrease and potential device damage

Engineering Contradiction:
Improvecontinuous detection capabilityVSAvoiddetection accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

A cooling plate is introduced as an intermediary component between the laser ranging sensor and the high-temperature environment. The cooling plate contains air flow channels that allow cooling air to pass through, creating a thermal barrier that protects the sensor from direct heat exposure while enabling continuous operation

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs pneumatic cooling by introducing cooling air through air inlet holes into the air flow channels within the cooling plate. This flowing air removes heat from the laser ranging sensor, allowing continuous detection without temperature-induced accuracy degradation or device damage

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Adaptability or versatility

If the laser ranging sensor operates in a high temperature environment, then the device can function in harsh conditions, but the infrared light sensitive elements expand or contract reducing detection accuracy

Engineering Contradiction:
Improveharsh environment operationVSAvoiddetection accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The cooling plate serves as a protective intermediary that shields the infrared light sensitive elements from direct thermal exposure. By maintaining a cooler microenvironment around the sensor through internal air flow channels, the plate prevents thermal expansion and contraction of sensitive components while allowing the device to operate in high-temperature environments

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If a cooling module is added to the detection device, then the detection accuracy and service life are improved, but the device complexity increases

Engineering Contradiction:
Improveservice lifeVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cooling function is merged with the protective enclosure structure. The cooling plate integrates air inlet holes, internal air flow channels, and air outlet holes into a single component that also serves as part of the device housing, eliminating the need for separate cooling system components and reducing overall structural complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cooling plate performs multiple functions: it serves as a structural component of the device housing, provides thermal management through internal air flow channels, and protects the laser ranging sensor from environmental damage. This multi-functionality reduces the need for additional components, maintaining simplicity while improving reliability

Inventive Principle:
Principle #6Universality (Multi-functionality)
